	* w32/pathstuff.c: Turned convert_vpath_to_win32() into a
	real function. This was done so that VPATH could contain
	white space separated pathnames. Please note that directory
	paths (in VPATH/vpath context) containing white space are not
	supported (just as they are not under Unix). See README.WIN32
	for suggestions.
	* README.WIN32: Added some notes about why I chose not to try
	and support pathnames which contain white space and some
	workaround suggestions.

-Port of GNU make to Windows NT and Windows 95 

-Builds natively with MSVC 2.x or MSVC 4.x compilers.

-

-To build with nmake on Windows NT or Windows 95:

-

-	1. Make sure cl.exe is in your %Path%. Example:

-	

-		set Path=%Path%;c:/msdev/bin

-

-	2. Make sure %include% is set to msvc include directory. Example:

-

-		set include=c:/msdev/include

-

-	3. Make sure %lib% is set to msvc lib directory. Example:

-

-		set lib=c:/msdev/lib

-

-	4. nmake /f NMakefile

-

-

-There is a bat file (build_w32.bat) for folks who have fear of nmake.

-	

-Outputs:

-

-	WinDebug/make.exe

-	WinRel/make.exe

-

-Notes:

-

-	This port prefers you have a working sh.exe somewhere on your

-	system. If you don't have sh.exe, port falls back to

-	MSDOS mode for launching programs (via a batch file).

-	The MSDOS mode style execution has not been tested too

-	carefully though (I use GNU bash as sh.exe).

-

-	I verified all functionality with a slightly modified version

-	of make-test-0.4.5 (modifications to get test suite to run

-	on Windows NT). All tests pass in an environment that includes

-	sh.exe. 

-

-	I did not provide a Visual C project file with this port as

-	the project file would not be considered freely distributable

-	(or so I think). It is easy enough to create one though if

-	you know how to use Visual C. 

-

-	I build the program statically to avoid problems locating DLL's

-	on machines that may not have MSVC runtime installed. If you

-	prefer, you can change make to build with shared libraries by

-	changing /MT to /MD in the NMakefile (or build_w32.bat).

+-- Notes/Caveats --
+
+GNU make and sh.exe:
+
+	This port prefers you have a working sh.exe somewhere on your
+	system. If you don't have sh.exe, port falls back to
+	MSDOS mode for launching programs (via a batch file).
+	The MSDOS mode style execution has not been tested too
+	carefully though (I use GNU bash as sh.exe). 
+
+	There are very few true ports of Bourne shell for NT right now.
+	There is a version of GNU bash available from Cygnus gnu-win32 
+	porting effort.  Other possibilites are to get the MKS version 
+	of sh.exe or to build your own with a package like 
+	NutCracker (DataFocus) or Portage (Consensys). 
+
+	Tivoli uses a homegrown port of GNU bash which is not (yet)
+	freely available. It may be available someday, but I am not in control
+	of this decision nor do I influence it. Sorry!
+
+GNU make test suite:
+
+	I verified all functionality with a slightly modified version
+	of make-test-0.4.5 (modifications to get test suite to run
+	on Windows NT). All tests pass in an environment that includes
+	sh.exe. Tested on both Windows NT and Windows 95.
+
+Building GNU make on Windows NT and Windows 95 with Microsoft Visual C
+
+	I did not provide a Visual C project file with this port as
+	the project file would not be considered freely distributable
+	(or so I think). It is easy enough to create one though if
+	you know how to use Visual C. 
+
+	I build the program statically to avoid problems locating DLL's
+	on machines that may not have MSVC runtime installed. If you
+	prefer, you can change make to build with shared libraries by
+	changing /MT to /MD in the NMakefile (or build_w32.bat). 
+
+	Program has not been built under non-Intel architectures (yet).
+
+	I have not tried to build with any other compilers than MSVC.
+
+Pathnames and white space:
+
+	Unlike Unix, WIN32 systems encourage pathnames which
+	contain white space (e.g. C:\Program Files\). These sorts of pathnames
+	are legal under Unix too, but are never encouraged. There is
+	at least one place in make (VPATH/vpath handling) where paths
+	containing white space will simply not work. There may be others
+	too. I chose to not try and port make in such a way so that
+	these sorts of paths could be handled. I offer these suggestions
+	as workarounds:
+
+		1. Use 8.3 notation 
+		2. Rename the directory so it does not contain white space.
+
+	If you are unhappy with this choice, this is free software
+	and you are free to take a crack at making this work. The code
+	in w32/pathstuff.c and vpath.c would be the places to start.
+
+SAMBA/NTFS/VFAT:
+
+	I have not had any success building the debug version of this
+	package using SAMBA as my file server. The reason seems to be
+	related to the way VC++ 4.0 changes the case name of the pdb
+	filename it is passed on the command line. It seems to change
+	the name always to to lower case. I contend that
+	the VC++ compiler should not change the casename of files that
+	are passed as arguments on the command line. I don't think this
+	was a problem in MSVC 2.x, but I know it is a problem in MSVC 4.x.
+
+	The package builds fine on VFAT and NTFS filesystems.
+
+	Most all of the development I have done to date has been using
+	NTFS and long file names. I have not done any considerable work
+	under VFAT. VFAT users may wish to be aware that this port
+	of make does respect case sensitivity.
+
+Bug reports:
+
+	Please submit bugs via the normal bug reporting mechanism
+	which is described in one of the texinfo files. If you don't
+	have texinfo for Windows NT or Windows 95, these files are simple
+	text files and can be read with a text editor.
